🔁 Build-it-from-shapes visual test
Has the AI build a 3D airplane from simple shapes, take pictures from nine angles, and fix whatever looks most wrong.
Use it when: You want to test how well an AI can see and improve its own visual work, or reuse the pattern for another 3D object.
🛑 Stops when: All nine views clear the score you set, or the budget runs out.
Copy this loop
Pick reference photos of [object, e.g. a Boeing 747], a scoring checklist, a target score of [X], and a limit of [N] rounds. Build the most realistic version you can from basic Three.js shapes. Set up a camera rig that screenshots the same nine angles every time. After each change, re-render and score all nine. Ask a critic to name the weakest feature and fix it without making other views worse. Keep the best version so far. Stop at the target score, no progress, or [N] rounds.
Review every change the agent makes before you keep it. Set a budget or round limit — the prompt includes one.
